An apparatus for making a semiconductor assembly and, specifically, interconnecting a semiconductor die to a carrier substrate. A method operational in a receiver device, includes monitoring one or more repurposed channels within a television broadcast frequency spectrum for data waveforms, wherein waveforms of different bandwidths coexist within the one or more repurposed channels, and at least a larger waveform has a first bandwidth larger than a channel bandwidth for each repurposed channel. An object identifier is created to identify one or more objects.
